537226 - zooming out generates black borders around images

Status: RESOLVED DUPLICATE of bug 468496

(Core :: Layout, defect)

Description

[Jan Rüegg]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.6) Gecko/20091216 Shiretoko/3.5.6
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.6) Gecko/20091216 Shiretoko/3.5.6

When doing a full page zoom on a page with some images, the images get a black border when I zoom out.

This is very ugly for images with a white background on a white border, like the google start page (see screenshots).

This does not happen when zooming in.

I'm using the firefox 3.5.6 out of the Archlinux repositories on x86.

Reproducible: Always

FF 3.5.6 on Windows XP

Additionally, images that 'hang' because they've not been fully downloaded are surrounded on all four sides by a similar border. But this is only when FireFox zooms out beyond 100%

Typically the HTML looks like this:
<a href="http://www.mysite.com/blah.php"><img border="0" height="150" width="150" src="http://www.mysite.com/images/image.jpg" alt="Blah" title="blah"></a>

The borders don't display if the oldwidth  (proprietary?) attribute is used like this:
<a href="http://www.mysite.com/blah.php"><img border="0" height="150" oldwidth="150" src="http://www.mysite.com/images/image.jpg" alt="Blah" title="blah"></a>

Works fine on Mac 3.6 and Vista 3.6/trunk
Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6
Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.3a5pre) Gecko/20100516 Minefield/3.7a5pre

Similar borders when zooming (although there's no need to zoom out to see them, they display reliably on certain zoom levels) on Mac trunk, but it may be a different issue: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.3a5pre) Gecko/20100516 Minefield/3.7a5pre

Does anyone see it on Linux 3.6 and trunk?

(and please don't confirm Core bugs in Firefox:General!)
